Re: Re : Interleaving Spurs: Letís Look at the Math
That is correct Sunita.  Now that we've explored the mismatches, I thought it appropriate to start quantifying the level of the spurs caused by these mismatches.

Re : Interleaving Spurs: Letís Look at the Math
There are several challenges to look out for while interleaving ADCs.  Spurs appear in the output band that outcomes from the inadequacies related with inter leaving ADCs.  The deficiencies are essentially misalliances between the 2 ADCs that are interleaved.  There are 4 elementary misalliances that outcome in spurs in the production of band.  These are gain mismatch, offset mismatch bandwidth mismatch and timing mismatch.

After looking at the performance metrics in the online ADC simulator tool it is a great time to look at another online ADC tool called the Frequency Folding Tool. It is a useful simulator that helps to understand the effects of aliasing in an ADC.
. I received a very good reader question from my last blog post regarding the various parameters that are reported by the tool. Letís take a look at an example and explore the parameters that are returned. In this example we will look at the AD9643-250.
Now letís look at the web-based evaluation tool. This does not require downloaded software to run as it is purely ran from the web
First, to make any ADC operate we need to set up the input stimuli.
We begin this series of blogs by taking a look at ADIsimADC, which is a quite relevant design tool for Jonathan Harris, an applications engineer in ADI's high-speed ADC group.
